Part.
Optimize, above-mentioned high intensity tunnel ventilation pipeline, layer of sand is filled with the gap.
After outer layer pipe is impacted, layer of sand can play the work of the pressure between inner buffer layer pipeline and outer layer pipe
With.
Optimization, above-mentioned high intensity tunnel ventilation pipeline, the support component includes supporting plate I and supporting plate II, support
Plate I is fixedly connected with inner layer pipe outer wall, and supporting plate II is fixedly connected with the inwall of outer layer pipe；The supporting plate I and support
Horizontal support bar I and horizontal support bar II are provided between plate II, one end and the horizontal support bar II of horizontal support bar I are hinged, horizontal support bar I
The other end be fixedly connected with supporting plate I；One end of the horizontal support bar II is hinged with horizontal support bar I, horizontal support bar II it is another
One end is fixedly connected with supporting plate II.
Optimization, above-mentioned high intensity tunnel ventilation pipeline, the angle of the horizontal support bar I and horizontal support bar II is more than 90 degree
Less than 180 degree.
Optimization, above-mentioned high intensity tunnel ventilation pipeline, the support component also includes an elastic metallic bar, elasticity gold
The two ends of category bar are fixedly connected with the middle part of horizontal support bar I and the middle part of horizontal support bar II respectively.
By elastic metallic bar supporting role, the relative position of fixed outer layer pipeline and inner layer pipe.
By the elastic deformation of elastic metallic bar, it can absorb outer layer pipe after failure by rupture occurs for outer layer pipe and apply
Plus the pressure of inner layer pipeline, prevent inner layer pipe from further rupturing.
Optimization, above-mentioned high intensity tunnel ventilation pipeline, the elastic metallic bar is curved metal bar.
Optimize, above-mentioned high intensity tunnel ventilation pipeline, spacer bar is preset with the rectangle prefabricated board I.
Spacer bar serves the effect of the intensity of increase rectangle prefabricated board I.
